I have Rook outfit without playing through Infamous difficulty?

Not that I'm complaining, but it seems like I already have it unlocked without playing through the difficulty. No, I didn't cheat, but I did read playing on Co-Op with someone who is on Infamous difficulty and completing the mission unlocks it.

Not sure if I remember ever doing coop with someone on that difficulty. All I know is that I didn't play the game since 2018 (when the New Game+ was introduced) and when I decided to start it up today again out of curiosity and because it now has New Game+, I noticed in my Special Outfits that it's unlocked. Cool, I guess.

I think that happened when the game went from Uplay to Ubisoft Connect, it was amongst a number of things that became unlocked.

That explains it. I remember when they said that Ubisoft Connect would unlock all rewards associated with games at the time, and the Rook outfit was something that could be unlocked through the Uplay Rewards as well apparently.
